DNA structure. DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).The order of these bases is what determines DNA's instructions, or genetic code.ach nucleotide contains a phosphate group, a sugar group and a nitrogen base.

It is a chain of chemical building blocks called nucleotides that are a combination of a nitrogen base, a sugar called deoxyribose and a phosphate group. The DNA molecule is shaped like a ladder that is twisted into a coiled configuration called a double helix.The nitrogen bases form the rungs of the ladder and are arranged in pairs, which are connected to each other by chemical bonds.t is a chain of chemical building blocks called nucleotides that are a combination of a nitrogen base, a sugar called deoxyribose and a phosphate group.
